How to compare older and newer Lookup fields on a object

Hi all,

I have a Account Lookup field on contact object. Whenever, the Lookup field value is changed to new value, a new case record has to be created with 'isTrue' checkbox checked.   

I want to know how tov write code to compare lookup field values before and after saving

Thanks in advance:)

    trigger ContactTrigger on Contact(after update) {
        for (Contact cont: trigger.new) {
            if (trigger.oldMap.get(cont.Id).AccountId != cont.AccountId && cont.AccountId != null) {
                //create new case here
                ​}
        }
    }
